The MAC Group has launched a new promotion that offers a free PocketWizard AC3 ZoneController ($79 value) to photographers who purchase a new PocketWizard MiniTT1 and FlexTT5 or two FlexTT5 radios for either Canon or Nikon. The PocketWizard MiniTT1 and FlexTT5 radios can be used to trigger any combination of TTL or manual flash units placed wherever desired, to illuminate the subject or scene being photographed. The PocketWizard AC3 ZoneController is the finishing touch that provides simple, finger-tip control of light output from three separate zones (A, B, C) of flashes or groups of flash units mounted on Flex TT5 transceivers, in either automatic-exposure or manual control. Running until 19th April, the MAC Group's mail-in programme is available only in the USA. For more information, check out the website below.
